Suppose we want to choose 4 objects, without replacement, from 16 distinct objects (a) How many ways can this be done, if the or

lys-0071 [83]

Answer:

a) 1820 ways

b) 43680 ways

Step-by-step explanation:

When the order of the choices is relevant we use the permutation formula:

$P_{n,x}$ is the number of different permutations of x objects from a set of n elements, given by the following formula.

$P_{n,x} = \frac{n!}{(n-x)!}$

When the order of choices is not relevant we use the combination formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

In this problem, we have that:

$x = 4, n = 16$

(a) How many ways can this be done, if the order of the choices is not relevant?

$C_{16,4} = \frac{16!}{4!(12)!} = 1820$

(b) How many ways can this be done, if the order of the choices is relevant?

$P_{16,4} = \frac{16!}{(12)!} = 43680$
